|This invention relates toitlieft` proof de:

vices for spare tire carriers of automobiles` and relates particularly to theft proof devices comprising shield members for preventing access to the means for securing spare tire carriers to automobiles. f

In a well known make of automobile,l which type constitute a great percentage .of auto-y mobiles in use today, a Y-shaped securing vzo A 'so to automobiles.

dotted lines;

member or carrier is'secured to a support on the automobile by means yof three bolts and nuts. After the carrier is in positionoii the car, a small measureof precaution against theft is taken kby upsetting' the ends of the bolts projecting: throughthe nuts. As an added measure of precaution, a lockis provided for locking the spare tire andy rim'to the carrier. .Y

It will be apparent that, although the spare tire is locked to the carrier, the nuts holding the carrier 'to the support may bereadily forced from their bolts and both the spare tire and carrier taken from the oar.

vAs a result ofthe present invention, a shield' member is provided to prevent access tothe aforementioned nuts, said shield being adapted to be locked inposition bymean's of the same lock which is provided for vsecuring the spare' tire vto the carrier.

- VOne ofthe objects of this invention is to; Vprovide a theft proof device for preventing vsecuring spare tires larged surface 27vhas anaperture`28 for re access to the means for Other objects and advantages will be apparent from the following ldescription and. the accompanying drawing, in which drawing:

view of the de- Referring more particularly to the draw*k ings, a V-shaped bracket or carrier is secured to asupport l1 of anV lautomobile by means o-f bolts 12 projecting from vthe sup' port 11 through the carrier and secured by means'of nuts 13; The bolts12are provided of such length as" to project through the nuts,

and the projecting portionsare upset as at 12"" to provide, in some measure, fortheir not being removable except by use efforce.

The upper members 14 of the Y-shapedcank 1 is' a face view ofa spare tire car-v rier 10 are provided with forked projections i 15 upon which the-rim 16 of the'spareti're 17 rests. Thelower member 18 is provided with a projection l9'comprising 'a bolt, the Ahead of which is embedded insaid member, and

which projectionfextends through one of the.r

As has been liereinbefoi'e stated, the nutsl3 are prevented, in aV small measure, from being i removed by the upsetting ofthe bolts12, butVV y f this'has not proven an adequate means of pro-r tection, since the nuts heretofore havebeen This invention pro-l vforced `from the bolts; vides'- a channeleshaped shield member 24 adaptedtojform a housing for -theflower part of the Y shapedcarrier l0, covering thenuts and thus preventing access thereto.

While a single embodiment of this invention is herein shown and described, it is to be understood that this device is not to be limited to the exact structure or details thereof, since various other forms will be apparent to one skilled `in the art and, consequently, it is to be limited only by the scope of the appended claims andthe prior' art.

I claim;

1. The combination with a spare tire car rier, a support, and a detachable securing member for seeming the tire carriei` to the support, or' means for preventing the removal of the tire carrier from the support comprising a shield member adjacent said securing member and having an aperture therein, a hooleshaped projection secured to sai d shield member and adapted to engage said support,

a lock nut having an aperture for registraf tion with said aperture in said shield niember, and alock for engaging said yregistering 2. The combination Withv a spare tire carn rier, a support, and a detachable securing to the support, of means 'for preventing the removal ot' the tire-carrier from the siiipport comprisadjacent said lsecuring member and having an vaperture therein, a lock nut having an aperture for registration with said aperture in said shield member, and a lock for engaging said registering apertures.

` 3. In athe-t preventing device for tire carriers, va Y-shaped carrier having securing means Jor attaching to a support of an automobile, a shield member extending over and preventing access to said securing means, said shield member having a hook extending ing a shield member between the upper forks of the Y and hoolf ing over the edge of said carrier, anda lock for securing said shield member in place.

4. In a theft preventing device for tire carriers, a forked carrier having securing means for attaching it lto a support on an autcimobile, a shield member overlying and preventing access to said securing means, said shield member having a hook tween the arms of the fork and hooking ovei' the edge of 'the carrier, and a lock for securingsaid shield in place. v

5. In a theft-preventing device tor tire carriers a Y-shaped cariier .having securing means for attaching to a support ot' an automobile, a shield member extending overk and preventing access to said securing means, said shield member having a hool; extending extending bebetween the upper Ylforlrs et the Y and hoolry over the edge `oi' the carrier,n and a lock for securino said shield member in lace. E

said shield having` an arm portion overlying the loiver leg portion oi the Y, said lock cooperating vvithsaid overlying arm portion.

6. In a theft preventing device for tire carriers, a Y-shaped carrier having securing means for attaching to a support og'r'an automobile, a shield member extending over and preventing access to said securingmeans, said shield member having a hook extending between the upper forks of the Y and hooking over the edge of the carrier, anda lock for securing said shield memberv in place, said shield having an arm portion overlying the' lower leg portion of the. Y, said lock ceoper ating with said overlying arm portion, said securing means being adjacent the central portion of the Y-shaped carrier. f Y

In Witness whereof, I have hereunto subscribed my name. f y j y JOHANNES BERG. A
